I have seen something like it happen in battle. A man was coming at me, I at him, to kill. Then came a sudden great gust of wind that wrapped out cloaks over our swords and almost over our eyes, so that we could do nothing to one another but must fight the wind itself. And that ridiculous contention, so foreign to the business we were on, set us both laughing, face to face - friends for a moment - and then at once enemies again and forever.
